Though the only change to the specs officially or well the listings between the above models is that version 1.0 came with the GDDR5X high-speed 9 GB/s version and 2.0 appears to have reverted to GDDR5 standard speed for the 1060 again for whatever reason.

A PCB comparison would be needed to tell if there's other differences which I thought was less of a thing these days but it seems it's still around doing things such as stripping down things and re-releasing the product again.

EDIT: Or perhaps I'm just misunderstanding.
(Still it is the same product so if the consumer isn't aware of the differing revisions and product number between the two that could be problematic.)
